* nvservices: mitigate abort with heavy load on the GPU processing thread.
This should fix Mario Tennis and LM3 regressions with syncpoints.
NOTE: Mario Tennis seems to have another issue related to the texture
cache that happens randomly when starting a match.
PS: Also add a debug logger for all known ioctl call to facilitate
debugging and add a missing UpdateMin in EventSignal.
